DeGette, D-Denver, and Lamborn, R-Colorado Springs, are coming from ideologically opposing viewpoints on the issue.

DeGette will listen in to 90 minutes today on the Anti-Injunction Act, which gives the Supreme Court justices the opportunity to wait until there is someone affected by the individual mandate before deciding whether it is constitutional. Precedent states that a tax requirement cannot be challenged until there is a "victim" or someone who has had to pay for it.

Lamborn will listen in tomorrow on whether the individual mandate that every U.S. citizen must buy health insurance is constitutional.

"Of course I’ll be listening and cheering on the side that says this is unconstitutional," Lamborn said this morning. "This will be my first time in person in the U.S. Supreme Court. I’m excited. I’m pumped up."

Colorado Attorney General John Sutherswill also be in the courtroom. He is one of 26 state Attorneys General who sued on the constitutionality of the law. Suthers was one of six state AGs who secured a seat in the three days of hearings, though he won’t attend Wednesday.

The Supreme Court doled out some viewing tickets to both sides of Congressional leadership and members worked channels over the weekend to secure a seat for a day to watch.
